    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.common.dynamic.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.meter.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs" id="cvs" width="237" height="196"&gt;
    [No canvas support]
&lt;/canvas&gt;
</pre>

    This is the code that generates the chart:
    <pre class="code">
&lt;script&gt;
    window.onload = function ()
    {
        var meter = new RGraph.Meter({
            id: 'cvs',

            max: 10,
            value: 5,
            options: {
                centerx: 116,
